Parcelization (File Geodatabase)

Description This dataset is available for download from: Parcelization (File Geodatabase) Parcelization, a measure of size and density of parcels in a localized area, is a development feasibility factor that is used in evaluating substations’ ability to support new utility-scale resources in long-term energy planning. A statewide dataset of parcel boundaries are used to develop this index. The parcels are converted into a 90-meter raster, containing values of a unique identifier reflective of Parcel APN. A focal statistics tool is used to count the number of unique parcels within a 0.5 mile radius of each parcel. This output is provided here and is an intermediate output to the final parcelization map. Users who wish to use this information to produce the final map should overlay parcel boundary data and extract the mean raster value within each parcel. The map is limited to the area considered with solar technical resource potential after a minimum set of land-use screens (referred to as the Base Exclusions) has been applied. More information on the methods developing this dataset as well as the main use of this dataset in state electric system planning processes can be found in a recent CEC staff report and workshops supporting the resource-to-busbar mapping methodology for the 2024-2025 Transmission Planning Process.数据集说明：本数据集可从以下渠道获取：地块化数据集（Parcelization，File Geodatabase格式）。地块化是衡量局部区域内地块规模与密度的指标，亦是评估变电站在长期能源规划中支撑新型公用事业级能源资源能力的开发可行性因子。本指标依托全州范围的地块边界数据集构建：首先将地块转换为分辨率90米的栅格数据，其中存储了对应地块APN的唯一标识符数值；随后通过焦点统计工具（Focal Statistics）计算每个地块周边0.5英里范围内的唯一地块数量。本次发布的该成果为最终地块化地图的中间产物，若用户希望利用本信息生成最终地图，需叠加地块边界数据，并提取每个地块内的栅格平均值。该地图的覆盖范围限定为经过最低限度土地利用筛选（称为"基础排除区"）后具备太阳能技术资源潜力的区域。有关本数据集的构建方法及其在州级电力系统规划流程中的主要用途的详细信息，可参阅近期发布的加州能源委员会（CEC）工作人员报告，以及为支撑2024-2025年输电规划流程中的资源到母线（resource-to-busbar）制图方法而举办的相关研讨会材料。
